Umnxeba Umnxeba: Ukulinganiswa koKhuseleko kwii-1,000 zeeFoni zeeSelula

I-EWG engenzi nzuzo inika isicwangco samahhala, esibanzi ukuhlola umngcipheko we-radiation

I-T-Mobile MyTouch 3G kunye ne -Android ye-Android yenkqubo yokusebenza , ekhuphisana kakhulu ne- iPhone 3G S ye-AT & T kunye nePalm Pre for Sprint, inesiqingatha sesibini somnxeba ophezulu kwi-cell phone ye-handset entsha, ukuhlawula umkhokeli wabathengi beefowuni ezili-1 kunye nee-smartphone.

Oko kukubamba umbuzo omkhulu kumnxeba owusebenzisa ngoku okanye malunga nokuthenga: Ngaba iifowuni zikhuselekile okanye ngaba zibangelwa ngumhlaza? Ngenye yeyona mibuzo endala kwifowuni yefowuni apho singenayo impendulo eqondileyo.

Iindaba ezilungileyo kukuba abaphandi bayaqhubeka beqhubela izifundo kunye nokutshisa ngemali (kwaye bacele imali engaphezulu ) ukuze bafumane iimpendulo ezichanekileyo.

Kodwa nje ngokutya kufuneka kubhalwe ngongoma wezondlo, ingxabano efanayo ingenziwa ukuba iifowuni zimele zihlume iziphumo zazo zemizi.

Okwangoku, ubuncinci sinomgangatho omiselweyo umbane wefowuni ulinganiswa kwaye ngamanye amaxesha unikwe ingxelo. Kubizwa ngokuba yi- SAR , emele umlinganiselo othile wokunyuselwa .

KwiNyakatho yeMerika, ukulinganiswa kwe-SAR yefowuni kulinganiswa phakathi kwe-0.0 kunye no-1.60 kunye ne-1.60 ebekwa yi-Federal Communications Commission (FCC) njengelona nqanaba eliphezulu lemisebe elivumelekile.

Ukusebenzisa umgangatho we-SAR wokulinganisa, ngoku ngoku sinombutho ongeyona inzuzo obizwa ngokuba yi-Group Working Group (EWG) eyapapasho ingxelo ebalulekileyo yokubhengezwa kwabaxhasi kwii- cell phone, ii-PDAs kunye ne-smartphones malunga nendlela ephuma ngayo imitha.

I-EWG, ngendlela, liqela elifanayo elipapasha ulwazi olukhuselekileyo lwe-Skin Deep cosmetic database.

"Sithanda ukuthetha ukuba iifowuni zikhuselekile," watsho isazi senzulu ye-EWG kwaye ukhokela umlobi wophando u-Olga Naidenko, u-Ph.D. "Kodwa asikwazi. Inzululwazi yakutshanje - ngelixa ingagqiba - iphakamisa imiba enzulu malunga nomngcipheko womhlaza wesetyenziso sefowuni ekufuneka iqwalaselwe ngophando olungakumbi. [Kodwa thina] sinokuthatha amanyathelo okunciphisa ukutyhila [ngoku]. "

Abantu abaneebhiliyoni ezi-4 emhlabeni othetha ngeefowuni okanye ama-60 ekhulwini labantu (ngokutsho kwe-EWG), i-270.3 yezigidi ze-wireless ababhalisile e-US okanye ama-87 ekhulwini kumaMerika ngo-Dec. 2008 (ngokubhekiselele kwi-CTIA) kwaye izifundo zifumana "ingozi ephezulu kakhulu yengqondo kunye neengcambu zesifo seengcingo phakathi kwabantu abasebenzisa iifowuni iminyaka engama-10 okanye ngaphezulu," umbuzo wokubaluleka kwakho kubalulekile kwaye uyazi.

Ingakanani Imfono Yefowuni Yakho? Ukuthetha ngefowuni yakho akufani nokuba ne-X-ray. Ukulinganisela izinga lakho lemitha, kodwa ngoku ungakhangela i-cell phone yakho kwi-EWG ye-radiation guide ukuze wazi ukuba uxoxisana nenye nge-SAR ephezulu (ayikhethwayo) okanye i-SAR ephantsi (ikhethwayo).

Nangona ezinye iisithuthi zeefowuni ziluhlu olu lwazi lwe-SAR (okt i-Verizon Wireless yenza oku kulungile), okwangoku akukho mgangatho kuwo wonke umashishini kuba akuzange kubekho isenzo sikaRhulumente sokufuna. Ezinye iithwali zichaza ulwazi kunye nabanye abangekho. Kodwa i-EWG iqokelele iifowuni zeefowuni kunye namazinga abo eSAR kwindawo enye.

Umzekelo weT-Mobile MyTouch 3G, umzekelo, unezinga eliphezulu lemitha ye-1.55 W / kg xa ibanjwe indlebe, i-EWG ithi ngokwemveliso yomnxeba. Eli nqanaba le-SAR lincinci ngaphantsi kwe-FCC-eligunyazisiweyo ngokusemgangathweni komthetho kwaye kunokukhathazeka kwabathengi.

Ngokwahlukileyo, ukulinganiswa kweSAR ephantsi kwefowuni kwisikhokelo se-EWG yi-Samsung Impression (SGH-a877) ye-AT & T, enezinga eliphezulu le-SAR lika-0.35 W / kg xa ligcinwe indlebe, i-EWG ithi ngokwe umenzi wefowuni.

I-EWG ithi iifowuni ze-iPhone 3G S ngezinga eliphakamileyo eli-1.19 W / kg kunye neePal Pre rates kwi-0.92 W / kg ephantsi.

Isikhokelo somlilo wefowuni ye-EWG senziwa kwi-Sept. 9, 2009 ngale mishini:

"Kwi-EWG, iqela lethu lezenzululwazi, iinjineli, iingcali zomgaqo-nkqubo, amagqwetha kunye neenkqubo zeekhompyutheni ziphosa ulwazi lwekarhulumente, iimpepha zomthetho, izifundo zenzululwazi kunye neemvavanyo zethu zelabhoratri ukuba ziveze izisongelo kwimpilo yakho nakwiindawo zokusingqongileyo kunye nokufumana isisombululo. Uphando lwethu lubangela ukukhanyisa amaqiniso anelungelo lokukwazi. "

Ngelixa silinde iimpendulo ezicacileyo malunga nokukhuselwa kwefowuni kunye nemisebe, ukulungiselela isikhokelo se-EWG kukunceda abathengi bathathe iifowuni kunye namazinga aphantsi e-SAR.

I-10 yeefowuni eziphezulu kakhulu ze-EWG kunye nee-smartphone (kunye ne-radiation ephantsi) zingabonwa ngezantsi kunye ne-10 ephezulu kakhulu (nge-radiation ephezulu). Ezi zixhobo zefowuni zibhalwe kwizinto eziphambili ukuya kwizona zilungele ukhetho oluhle kakhulu kwaye ziqale ngoluhlu olubi kunabo bonke.

Ukongezelela ukwazi i-SAR yakho yangoku okanye entsha yefowuni ye-SAR, i-EWG iphinda icebise iingcebiso zokukhusela ezisibhozo zokukunceda ngokukhawuleza kwaye ngokukhawuleza unciphise i-cell phone yakho. Nazi ezinye iingcebiso ezintlanu nakwi-Barton Publishing.

Isikhokelo se-EWG sikuvumela ukuba ukhangele ukwenza kunye nokwenza imodeli yakho-ngokukhawuleza njengoko kusekuhlaleni lwazo - kwaye unokufumana iifowuni ngomnxeba wefowuni kunye nomenzi weselfowuni. Unokufikelela kwi-EWG epheleleyo yefowuni ye-radiation guide apha .
